SB 689 amends Michigan's farmland preservation law to expand when landowners can give up (relinquish) farmland from development rights agreements. It adds two new scenarios: 1) land with pre-existing structures (up to 5 acres), and 2) land for a farm operator's residence (up to 2 acres), both requiring approval from local government and the state land use agency. If relinquishment occurs, landowners must repay tax credits received under the agreement, plus interest, via a lien recorded against the property. This directly affects farmers with existing farmland preservation agreements who wish to develop or use portions of their land for specific purposes.

SB 273 extends the expiration date of a fee imposed on agricultural operations to fund water quality protection programs. This bill amends Michigan's 1994 law (MCL 324.8715) to remove the sunset provision, ensuring the fee remains in effect indefinitely. It directly affects agricultural businesses that pay this fee, which supports local water quality initiatives. The bill was enacted with immediate effect after governor approval on October 7, 2025.

SB 396 updates Michigan's air pollution laws to include specific regulations for carbon sequestration projects. It directly affects companies and organizations that capture and store carbon dioxide underground to reduce emissions. The bill adds new rules requiring safe storage practices, reporting, and oversight for these projects under the existing air pollution control framework. This amends current law to create a clear regulatory path for carbon sequestration as part of the state's air quality management.

SB 394 establishes that landowners in Michigan automatically own the pore space (open spaces in underground rock formations) beneath their property, which can be used for storing substances like carbon dioxide. This means property buyers inherit pore space rights unless the seller explicitly transfers or excludes them in the sale agreement. The bill requires clear language in property transfers to sever pore space rights from surface ownership, protecting existing mineral rights and surface access for oil/gas operations. It does not affect mineral rights or existing agreements but requires Senate Bill 395 to pass simultaneously for full implementation. The bill aims to clarify ownership for future resource storage projects while maintaining current legal frameworks.
